DTC P176E-00; Clutch Stroke Sensor/Starter Interlock Switch Correlation Problem: Notes

DTC DETECTION DESCRIPTION

DTC P176E:00	Clutch stroke sensor/Starter interlock switch correlation problem
DETECTION CONDITION	Correlation malfunction between clutch stroke sensor and starter interlock switch. If the clutch stroke sensor circuit voltage above 4.9 V or below 0.1 V for 10 s, the PCM determines that the clutch stroke sensor circuit has a malfunction. CPP switch stuck ON or OFF. Starter interlock switch stuck ON. Diagnostic support note This is a continuous monitor (other). The check engine light does not illuminate. FREEZE FRAME DATA is not available. Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Not applicable
POSSIBLE CAUSE	CAUTION: Inspect the CPP switch with it installed to the clutch pedal, otherwise the CPP switch may not operate normally after inspection. If the CPP switch is removed from the clutch pedal, replace the CPP switch with a new one. Inspect the starter interlock switch with it installed to the clutch pedal, otherwise the starter interlock switch may not operate normally after inspection. If the starter interlock switch is removed from the clutch pedal, replace the starter interlock switch with a new one. CPP switch, clutch stroke sensor and/or starter interlock switch loose Starter interlock switch connector or terminals malfunction Starter interlock switch malfunction PCM connector or terminals malfunction Short to ground in wiring harness between starter interlock switch terminal A and PCM terminal 2BD CPP switch connector or terminals malfunction CPP switch malfunction Open circuit in wiring harness between CPP switch terminal B and body ground Short to ground in wiring harness between CPP switch terminal A and PCM terminal 2J Short to power supply in wiring harness between CPP switch terminal A and PCM terminal 2J Open circuit in wiring harness between CPP switch terminal A and PCM terminal 2J Clutch stroke sensor connector or terminals malfunction Short to ground in wiring harness between the following terminals: Clutch stroke sensor terminal C-PCM terminal 2BG Clutch stroke sensor terminal B-PCM terminal 2M Short to power supply in wiring harness between clutch stroke sensor terminal B and PCM terminal 2M Clutch stroke sensor circuits are shorted to each other. Open circuit in wiring harness between the following terminals: Clutch stroke sensor terminal C-PCM terminal 2BG Clutch stroke sensor terminal B-PCM terminal 2M Clutch stroke sensor terminal A-PCM terminal 2AH Clutch stroke sensor malfunction PCM malfunction
